"...though G2F has this feature and (at least in my friends version of poser) her boobs are rotated in oposing direction at all times unless you limit her pectoral bones to zero roatation in the parameter editor." G2F works perfectly fine on my machine, including her automated breast movement. Did your friend upgrade his version of Poser, the G2F installer, the companion files and also the DSON importer to the latest versions ? DAZ is constantly updating them, so it's easy to fall behind a version or two.
